CoTweet, a Twitter application made with businesses in mind, announced today that it received $1.1 million in funding, joining a small — yet growing — group of Twitter-focused startups that have received investor financing. The investors behind CoTweet include Baseline Ventures, First Round Capital, Founders Fund, SV Angel, Maples Investments and Freestyle Capital.

CoTweet, which publicly launched in beta today, is a collaboration platform that lets multiple people at a company send tweets on up to six corporate Twitter accounts and keeps the messages in sync across all the accounts. The San Francisco-based upstart is the newest member in the small club of funded Twitter-focused startups, which altogether have been backed with quite a chunk of cash. As of June, ChubbyBrain found that VC firms and angel investors have invested around $23.3 million in 11 Twitter-related startups, including Stocktwits, Twitvid and Twitterfeed.

The CoTweet platform works with Bit.ly, a URL shortener created by New York-based incubator Betaworks, which received $2 million in funding back in March. CoTweet’s clients already include big corporate players such as Whole Foods, JetBlue and Microsoft — not bad for a year-old startup.
